    Abstract: The present invention relates to a method for manufacturing carbon nanotubes continuously and an apparatus used therefor. The method for manufacturing carbon nanotubes continuously comprises the steps of a) generating carbon nanotubes by making reactive gas, which includes a carbon source, reducing gas and inert gas, react with a catalyst; b) separating carbon nanotubes and mixed gas, which is a by-product, from the product of the reaction; and c) recirculating part of the gaseous component of the separated mixed gas into step a) and discharging the remainder without separating and refining the gaseous component. The method and the apparatus according to the present invention can increase process efficiency greatly by controlling the accumulation amount of a side reactant to a proper level without separately using a gas separation unit or a separation process for separating a certain component of discharged gas.
